AUTOMATIC RELE ASlN-G MECHANISM FOR PHONOGRAPHS, 840.

SPECIFICATION forming part of Letters Patent No. 694,705, dated March 4,1902.

Application filed November 9, 1900- Serial No. 35,946. (No model.) I

This invention has relation to an automaticreleasing mechanism forphonographs; and in such connection it relates to the construction andarrangement of such a mechanism.

The principal object of my invention is to provide in a phonograph adraw-bar, a lever adapted to be operated when said draw-bar is pulled inone direction, an arm controlled by said lever, a sound boX or carrieradapted to descend upon the operation of the lever, a clockworkmechanism adapted to be set in operation upon one movement of the arm, adriving-worm and drum controlled by the clockwork, means for couplingthe sound box or carrier to the driving-worm when the carrier descends,a record secured to the drum and adapted to be engaged by thereproducing mechanism of the sound-box, a hook adapted to retain thelever and its arm in operative position, a stop traveling with thesound-box carrier and adapted to release the hook at the completion ofthe movement longitudinally of said carrier, and a spring adapted toreturn the lever and arm to normal inoperative position when said hookis released and to elevate the sound-box carrier away from the drum andrecord.

The nature and scope of my invention will be more fully understood fromthe following description, taken in connection with the accompanyingdrawings, formin gpart hereof, in which- Figure l is a side elevationalview of a phonographic apparatus embodying main features of myinvention. Fig. 2 is a top or plan view of Fig. 1. Fig 3 is a detailview of the lockin g mechanism for securing the starting-lever mechanismin elevated position. Fig. 4 is a top or plan view illustrating thelever mechanism in conjunction with the clockwork. Fig. 5 isa sectionalview illustrating the driving shaft or drum, and Fig.

6 is a detail view of the connection between the spring and thesound-box slide orcarrier.

, Referring to the drawings, the apparatus ;a bolt or pin 0 and carriesat that end a counterweight c. A draw-bar d is provided with a button eand hook'f and is normally under tension of a spring a; The lever g ispivotally secured, as at k, to the framework of the phonograph andcarries an arm g. The lever g and a lever it both carry arod The lever gis underthe influence or tension of a spring Z. A lever n, under tensionof the spring 0, is pivoted to the framework, as at m, and carries thehook or. The clockwork p is located in a housing below the phonographproper and is started by the cord '1" and wheels 15. The cord 7"actuates the drum 8 and the wheels 75 actuate the worm u. The worm u' isengaged by a'nut 01, secured to the sound-box carrier w. The stop y,normally pressing against astop z, is also carried by the membrane orsound-box carrier or, which carrier m is under the influence of a spring6. The lever g, by means of a chain q, is connected witha brake-lever awhich controls the clockwork 9, and when elevated starts said clockwork.The clockwork 9 stops upon the descent of the lever g.

The operation 01": the mechanism is as follows: A coin sliding through apassage impinges upon alever a and causes the latter to tilt upon anaxis or fulcrum b and to thereby free or clear a pin 0. This pin 0 ismounted upon a draw bar d, which can be drawn outward by means of thebutton 6 when its pin 0 is clear of the lever a. The draw-bar d isprovided at its inner end with a hook f, engaging a lever-arm g, pivotedon the pin 70. The pin "k, in conjunction with a lever h, carries across-bar t'. A spring Z tends normally to retract the lower end of thelever g and to depress the arm 9, connected thereto. The arm g in movingupward against the tension of the spring Z presses back a lever '22,fulcrumed or pivoted, as at m, against the tension of a spring 0. A book7?. on the end of the lever'n serves to lock the arm g in its elevatedposition. The arm 9' is connected by a chain q with a clockwork 01'similar motor 1). A spring 0 (see Fig. 4) presses the brake-lever aagainst a brakedisk e located on the controlling or governor shaft (1for the motor p when the arm g is in its lowermost or inoperativeposition, and hence in the normal position of the lever a and arm g themotor 19 is inoperative. This chain q is connected with the brake-levera which is under tension of the spring 0 and is pivotally secured, as at11 (see Fig. 4,) to the framework of the machine. When, however, thelever g is shifted by the draw-bar d to elevate the arm g into lockedconnection with the lever 71 and its hook it, as illustrated in dottedlines in Fig. 1, the brake a is released by the chain g from the disk eand the motorp is permitted to operate. The clockwork-moto r 11 operatesthe phonograph cylinder or drum 8 by means of a belt or band 1', and themotor 1) also operates a screw-shaft u by means of gears t. The screw ordriving shaft u is connected by a nut 11 with the slide or carrier cc,which carries the membrane or sound-box w. (See Figs. 2 and 5.) Thiscarrier 00 has been lowered by the movement of the lever g outward,since the upper end of said lever g slides from under the beveledprojection I) on the free end of said carrier 00. When the carrier a: islowered, the sound box or receiver w is brought into operative position,with the record placed upon the drum or cylinder 3. When the sound -boxto has traversed the record, a pin y on the carriera; impinges upon acatch .2, which causes the lever n to retract its hook it against thetension of the spring 0 away from the arm g. This arm g when released isdepressed by the spring Z, and its lever g is forced inward to elevatethe projection b and carrier m away from the drum 8. The draw-bar d isnormally forced inward when the lever g returns to its normal positionby means of a spring a. At the same time the lever a, bymeans ofacounterweight 0, falls to its normal position to bring the pin 0 inlooking engagement with the draw-bar d and prevent its withdrawal untilanother coin is placed in the apparatus.

When the carrier :0 for the sound-box w descends, the nut o engagesfirmly the driving screw-shaft a, and the carrier is moved forward bysaid shaft. When, however, the carrier as is elevated by the lever-armg, the nut v is released from the shaft a, and aspiral spring e, mountedupon the rod (1', returns the carrier m to its normal position. Thespring 6 is fastened at one end to the framework of the apparatus and atthe other end to the carrier and is extended by the movement of thecarrier along the shaft u. Vhen the arm g and lover g assume a normalposition, the chain q is slackened to permit the brake a to impinge uponthe disk e and to stop the motor 1).

Having thus described the nature and object of my invention, What Iclaim as new, and desire to secure by Letters Patent, is

In a phonograph, a draw-bar, a lever adapted to be operated when saiddraw-bar is pulled in one direction, an arm adapted to be elevated bysaid lever, a sound box or carrier adapted to descend when said lever isoperated, a clockwork mechanism adapted to be set in operation when thearm is elevated, a driving-worm and a drum adapted to be set in motionby the clockwork, a coupling means adapted to connect the sound-boxcarrier to said driving-worm when the carrier descends, a record securedto the drum and adapted to be engaged by the sound-reproducing mechanismof the sound-box, a hook adapted to retain the lever and its arm inoperative position, a stop traveling with the sound-box carrier andadapted to shift said hook at the completion of the longitudinalmovement of the carrier, and a spring adapted to return the lever andits arm to normal inoperative position and to thereby elevate thesound-box carrier away from the drum and record.

In witness whereof I have hereunto signed my name, this 6th day ofOctober, 1900, in the presence of two subscribing witnesses.
